Application May 10, 1945, Serial No. 593,008

1 Claim. 1

My present invention, in its broad aspect, has to do with improvements in citrous fruit squeezers, especially lemons and oranges, and has means for thoroughly extruding the juice, by both rotation and squeezing, straining the same, and dispensing the strained juice into a portable container or the like. More particularly, my invention is designed to provide an improved juice extracting, straining and receiving unit wherein the parts may be readily cleaned, which presents a pleasing appearance as a kitchen or table accessory, and wherein the juices are delivered directly into an improved receptacle in the form of a pitcher which is an element of the unit but which may be used to receive and transport and serve the juices at table if so desired. Furthermore, my invention provides an improved arrangement whereby the half lemon or orange is turned by the use of one hand while suitable pressure for squeezing is applied by the other hand in a convenient manner, and my squeezing and turnin devices are improved, simplified, rendered easily cleanable, and are most practical for the purposes intended while the support is simple and sturdy and properly mounts the removable juice container.

Other and equally important objects and advantages of my invention will be apparent from the following description and drawings, and it is pointed out that changes in form, size, shape, construction and arrangement of parts is permissible and within the purview of my broad inventive concept and the scope of the appended claim.

In the drawings wherein I have illustrated a preferred form of my invention- Figure 1 is a top plan view;

Figure 2 is a side elevation;

Figure 3 is a section on the line 3--3 of Fig ure 1;

Figure 4 is an elevation of the supporting standards, supporting arm for the lever, and downwardly inclined floor for the squeezer elements and strainers;

Figure 5 is a top plan view of the structure shown in Figure 4;

Figure 6 is a top plan view of the upper and rotatable squeezer element;

Figure '7 is a top plan view of the lower and fixed squeezer element;

Figure 8 is a top plan view of the cup-shaped receptacle in which the squeezer elements fit;

Figure 9 is a detail of the strainer fitting in the bottom opening of the cup-shaped receptacle.

In the drawings wherein like characters of reference are used to designate like or similar parts throughout the several views: 7

The numeral I designates the circular metal base, which has a central circular depression 2 and a downwardly extending, outwardly flared or angular annular foot or supporting flange 3 on which the base rests. Adapted to seat in the depression 2, to be prevented from accidental displacement from the baseis a glass juice pitcher or container 4 which has a pouring nozzle 5 and is portable to be lifted ofi of the base when the desired amount of juice is contained therein. Mounted on the base, and having feet 6 are vertically and inwardly inclined supporting standards 1 which are ribbed as at 8 to stiffen their structure, and preferably integrally formed at their top edges is a downwardly inclined, dished, or disk-shaped, circular floor or tray 9 having a central opening Ill. Fixed to one of the standards is an upwardly and outwardly inclined arm II which has an upstanding ear 12 to which is pivoted as at l3 a horizontally positioned squeezer operating lever [4 of U-shaped construction in cross section and having a handle end l5 opposite the arm ll. Seated on the floor 9 is a cupshaped receptacle l5-see Figure 8-having upstanding beaded'side flanges l6 and an inclined or disk-shaped bottom I! having a central opening 18 registering with opening [0 and having an annular depending flange or nozzle [9 fitting through the opening III, a strainer Mia-see Figure 9which is annularly flanged to fit into the depending flange or nozzle [9. The receptacle has opposed inwardly directed supporting bosses 20 on its bottom, one of which is ribbed as at 2| to support the lower squeezer element 22 which has an opening 23 fitting over the rib 2| to prevent its rotation with respect to the receptacle.

The glass juice pitcher or container 4 is directly beneath the openings l0 and I8 and flange or nozzle l9, as shown in Figures 2 and 3.

The lower stationary or fixed squeezer element 22 has a central conical or domed part 24 which is formed with equally spaced radiating ribs 25, and an annular outwardly extending flange 23 provided with spaced openings 21. The flange seats on the bosses 20 and the opening 23 is formed in the flange as shown in Figure 7. The half section of citrous fruit to be squeezed is pressed down on the domed part 24.

The operating lever M has a sleeve-like formation 28 between its ends which is fixer to a tubular bearing 28a. dor a vertical shaft 29 one end of which is threaded as at 30 and the other end squared to receive thereon the upper and rotav1., tive squeezer element 3! which is similar in shape to the domed part of the lower squeezer element 22 to engage the lemon or orange to be squeezed therebetween. The rotating squeezer element St is internally ribbed as at 32, and an operating handle 33 has its arm 34 threadedly engaged with the threaded end 30 of the shaft 29 whereby to rotate the upper 'squeezer element. wl'rile said squeezer element is pressed downwardly-by pressure on the lever 14 thereby both squeezing (or pressing) and rotating the lemon or orange or other citrous fruit to fully and completely remove all juices which pass down through the noz'ZleTtE or conand are strained and pass into the pitcher tainer 4.

l '15: From the foregoing, it is believed thatthe operation and advantages of my invention will'be ap- V parent, but it is again emphasized that inter f pretation of the scope of my invention should only 'be'conclusive-when made inthe light of the subjoined claim.

I claim: v p g 'In a fruit juicexextractonfor "citrus limits, the

zontally disposed platform {having -a downwardly dishedfloor with a centrally positioned out-let opening, a removable cup-shaped receptacle also having .a downwardly dished lower surface corcombination, which comprises, an-elevated horiresponding with the --f1oor ofthe platform and havi-ng' a centrally disposedopening witha .-forwardly extending annular flange providing "a spout positioned in the centrally disposed opening of the floor, a strainer removably mounted in said spout, an upwardly extending domeshaped lower squeezer element with a horizontally disposed outwardly extending perforated annular flange lireely positioned in the receptacle, and an upper complementary squeezer element having a hand actuated lever and a crank by which the element is manually rotatedhinged to the plat- 7 form andadapted to hold one-half ofan orange or the like on the said lower squeezer element.
